/members-area/personalblogs/b/blog/posts/oag001-op-amp-amplifier-and-filter-prototype-pcbI never find it easy to build op-amp prototypes using surface mount components. One can buy an adapter PCB that converts SM to through hole pins compatible with 0.1inch breadboards or prototype boards. But it is still difficult to wire up the resistoen-USTelligent Community 12https://community.element14.com/members-area/personalblogs/b/blog/posts/oag001-op-amp-amplifier-and-filter-prototype-pcbTue, 26 Apr 2016 14:44:28 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:c7880196-1125-46ce-8c9b-853b2b293e6cmichaelkellett2<p>I long ago gave up attempting lash up prototypes of op-amps or anything else - some people still do wonders with dead-bug (ing) or birds&#39; nests but I go straight to a real board (if analogue often preceded by simulation).</p><p>&nbsp;</p><p>Have you looked at OPA192 (2484554) - not sure about driving long wires (haven&#39;t tried) but amazingly good offset, bias current, common mode range etc.</p><p>&nbsp;</p><p>I&#39;m just finishing an analogue (mostly) board with 13 of them on.</p><p>&nbsp;</p><p>MK</p><img src="https://community.element14.com/aggbug?PostID=21644&AppID=293&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/members-area/personalblogs/b/blog/posts/oag001-op-amp-amplifier-and-filter-prototype-pcbTue, 26 Apr 2016 13:27:52 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:c7880196-1125-46ce-8c9b-853b2b293e6cD_Hersey1<p>These circuits are so useful!&nbsp; Even better with some &#39;wire-wrap&#39; area to set up things like voltage references.&nbsp; Not to be &#39;that guy,&#39; but I observe that AD boards of this type throw in shunt caps on the input Rs as well:</p><p><a class="jive-link-external-small" href="http://www.analog.com/media/en/technical-documentation/application-notes/AN-732.pdf" rel="nofollow ugc noopener" target="_blank" title="http://www.analog.com/media/en/technical-documentation/application-notes/AN-732.pdf">http://www.analog.com/media/en/technical-documentation/application-notes/AN-732.pdf</a> </p><img src="https://community.element14.com/aggbug?PostID=21644&AppID=293&AppType=Weblog&ContentType=0" width="1" height="1">
